THOMAS E. BARBER, OF ROCHESTER, MINNESOTA.

WINDOW-FASTENING.

To all nrhont it nuty concern.-

Be it known that I, THOMAS E. BARBER, a citizen of the United States, residing at Rochester, in the county of Olmsted and State of Minnesota, have invented new and useful 1mprovements in l/Vindow-Fastenings, of which the following is a specification.

This invention has relation to window-fasteners of the kind designed to hold the sashes in place when either is in raised or lowered position.

It is designed to provide improvements which will afford a simply constructed and operated efficient and durable device for the purposes mentioned.

The drawings are to be referred to as forming a part of this specification.

Of the drawings, Figure 1 is an outside view of the invention represented as applied to a window-casing and operating against asash movable up and down. Fig. 2 is a similar view showing the device with the outside plate removed and some of the parts in dotted lines. Fig. 3 is a view similar to Fig. 1 with the outside plate only removed and the rollers in withdrawn position. Fig. 4 isa view like to Fig. 3, but showing the rollers as released.

The same characters of reference designate like parts or features in all of the views.

In the drawings, 1 designates the base-plate, which is adapted to be secured to a windowcasing 2, and 3 is a front or covering plate, which is spaced from the base-plate by blocks 1 at the opposite ends, which are held in place by small screws 5. There are end plates 6 6 and a back plate 7, so that a complete metallic casing for inclosing the most of the working devices is provided.

8 and 9 designate the rollers or wheels for operating against the sash and may be of rubber or rubber-bound They are each eccentrically journaled on axle-pins 8 and 9, fixed in the front and back plates. Aspring 10, connected at its ends to the peripheries of the rollers in the'rear, tends to draw upon the rollers and turn them on their axes and throw them forward out of the box. Screweyes 11 11 are turned into the sides of the rollers, so as to facilitate turning them back to position and away from engagement with the sash. The front plate is provided with notches 12 13 for the reception of the shanks Specification of Letters Patent.

of the screw-eyes, and a spring 14, fastened to the outside casing, cooperates with the said notches to retain the said shanks in place when they are withdrawn and allow them to be readily released when it is desired they shall be. casing to admit of screws being passed therethrough to secure the said casing to the window-frame or the like in place where it may act against the sash or the like.

Supposing the device to be complete and in place on the windowframe, as shown, the sash may be raised to the position desired, and by taking hold of the screw-eyes 11 11 they may be operated to move the rollers and allow them to turn on their eccentric axlepins and fly forward out of the casing against the sash by the tendency of the spring 10 acting thereon, and so hold the sash against being moved up or down. The spring 10 is shown as made of rubber, though it may be made of any suitable material and employed in any suitable way. When it is desired to lower the sash, the user by engaging the heads of the screw-eyes between the thumb and linger of the hand may press them together, turning the rollers or wheels 8 and 9 against the stress of the spring 10, so that the shanks of the screw-eyes will enter the notches 12 13 of the front plate and the spring Hyielding will allow them to pass and engage and hold them against moving out again until purposely released. hen the sash is raised, to lock it in position the operator simply presses on the heads of the screw-eyes or pinches together the ends of spring 14 to release the shanks from locked position and allow the rollers to fly out against the sash.

The peripheries of the rollers or wheels 12 13 may be roughened where they engage the surface of the window-sash, if desired.

Anything that will serve the function of the screw-eyes will answer as well to be used. They are used as happening to be suitable.

The device as awhole is compact, convenient, and efiicient for the purpose for which it is designed.

I claim The combination with the casing, having the front plate notched, as described, of the rollers eccentrically journaled in the casing, a spring acting upon the rollers to move them There are holes 15 formed through thein one direction to throw them out into hold- 1 In testimony whereof Iafiix my signature in ing position, screw-eyes turned into their presence of two subscribing witnesses. sides to turn the rollers 1n the opposite position, the said notches in the front plate being rlHOMAS BARBER arranged to receiye the shanks of the screw- Witnesses: eyes, and a sprlng to cooperate with the GEO.
